boat ramp construction methods
Boat ramp construction: best method. the best method for constructing the underwater portion of a boat ramp is to cofferdam the area, pump the water out of the site, and then pour and dry the ramp in place. this method gives you the best quality control and overall final result. however, if you’re using a traditional cofferdam, you need to.

Over 15% and the grade is too steep for many vehicles to pull the boat and trailer out of the water. we build mostly cast-in-place reinfored concrete ramps and improve traction on the ramps by using a "grooving tool" for finishing. the grooving tool is a flat plate with 1" angle iron welded to it at about 3" spacings..
